Direct indication is described as the true and instantaneous reflection of aircraft attitude on which display?

• A. The attitude indicator's miniature aeroplane relative to the horizon bar
• B. The airspeed indicator
• C. The altimeter
• D. The vertical speed indicator

Answer: (A)

Direct indication means the instrument shows the aircraft’s actual orientation in real time. The attitude indicator does this by using a gyroscopic horizon display with a fixed miniature airplane. When you bank or pitch, the horizon line moves relative to that fixed airplane, giving you an immediate, intuitive read of roll and pitch. The other instruments don’t depict attitude: the airspeed indicator shows speed, the altimeter shows altitude, and the vertical speed indicator shows climb or descent rate. So the attitude indicator’s horizon-and-airplane presentation is the true, instantaneous reflection of attitude.
